CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 236,364, dated January4, 1881.

Application filed March 19, 1880.

To all whom it may concern Be it known that 1, WILLIAM Seorr, of Maiden,in the county of Middlesex and State of Massachusetts, have inventedcertain new and useful Improvements in Couplings for Cars, of which thefollowing is a specification.

This invention relates to improvements in car-couplings described in thespecification accompanying mypending application for Letters Patent oncar-couplings; and it consists more particularly in the construction ofthe shackling-pin and its arrangement and operation in combination withthe shackling-link, all substantially as hereinafter described.

In the accompanying plate of drawings this improvement in couplings forcars is illustrated, Figure 1 being a side elevation of one of thecouplers; Fig. 2, a vertical longitmlinal section; Fig. 3, alongitudinal horizontal section on line 00 :r, Fig. 1; and Fig. 4, afront view of Fig. l, with the sh ackling-link in crosssection.

In the drawings, A represents one of my improved couplings for cars; B,a jaw arrangedin a vertical positign and projecting from the car atright angles to the end of the car, its upper end being shaped to makeand form a buffer, C. The front end, a, of lower part b of the jaw Binclines downward, as shown at d, and on each side of said lower part ishung a shackling-link, D, for which a rest, 6, is provided, suitablyshaped and located to limit the upward and downward swing of the link D.So far the several parts as described are substantially the same asshown and described in the pending application before referred to, andthe present improvements will now be fully described.

E is the shackling-pin. This pin is shaped as shown in the drawings,having an upright portion,f, and a toe portion, {1, projectingsubstantially at a right angle therefrom toward and over the incline (Zof the lower part ofjaw B. The upright portion f is square incrosssection, and is adapted to move freely up and down in a verticalsocket, h, in the upper part of jaw B. The toe portion 9 and the lowerend, I, of upright portion, which at such part is round 1ncross-section, rest in a correspondingly-shaped socket or recess, m, onthe upper side of the lower part, b, of the jaw, which (No model.)

socket serves as a seat for the shackling-pin, and also prevents anylateral play of the lower end of the pin and undue strain on its uprightportion when the cars are coupled.

The coupling as above described is selfoperating, and when two cars,each provided with one of these couplings, are brought together, end toend, the shackling-link of the car which then happens to lie the higherat its outer end slides up the shackling-link of the other car as thecars approach each other, and then up the incline d of the lower part ofthe jaw, and, passing under the toe portion 9 of the shackling-pin,between it and the incline, the pin is forced upward, and when the endof the shackling-link has passed beyond thepin,it (the pin) will then,by its own weight, drop through the loop of the link into its seat inthe lower partof the jaw, when the cars will be coupled. To uncouple thecars, raise the pin, when the link can easily be removed. The pin can beprovided with a cord or chain at its upper end for this purpose.

The back portion of the pin E can be inclined, as shown at n in thedrawings, so that the pull of the link when the cars are coupled willtend to keep the pin in its seat, and thus prevent the accidentaluncoupling of the cars. The toe end of the pin can have its under sideshaped as shown in dotted lines in the drawings. Constructing theshackling-pin with a toe-projection so far forward insures the entranceof the link between it and the incline face of lower part of the jaw,and thus the easy and sure raising of the pin and consequent shacklingof the cars.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The draw-head A, constructed with the jaws B O, the latter projectingbeyond the former to serve as a buffer, the link D, pivoted in andembracing the lower-jaw, and the pin 0, tixe'd on the lower jaw forlimiting the movement of the link, in combination with the looseshacklingpin having the forward-projecting toe, all as herein shown anddescribed.
